Title: Abrasive tools, esp. rotatable grinders - having diamond or boron nitride crystals embedded in metal layer bonded to support, and covered with resin
Inventor: TAUSCH EDWIN MICHAEL
IPC: B24D5/02
Filed: 1976-09-25
Abstract: Abrasive tool has a supporting body, e.g. a steel cylinder, and a large number of diamond or cubic boron nitride crystals, partly embedded in a metal layer bonded to the supporting body. A resin layer covers the metal layer and partly encloses the crystals, the latter being visible at their ends opposite to the supporting body. The metal layer effects very strong bonding of the crystals to the supporting body. The resin layer supports the crystals against detachment, and also prevents the filling of the tool with waste from the workpiece being ground. Heat is efficiently dissipated via the metal layer. The tool has a high abrasive working surface with a long operating life.

Patent DE-2733013-A1 (DE)
Inventor: BOUWMAN JOHANNES ERNEST
IPC: B23Q7/12
Filed: 1977-07-21
Abstract: The method is intended for those thread-rolling machines which have a stationary rolling element and a rolling element driven by a rotatable member. The movement of the rotatable member is divided into a predetermined number of movement steps. This number is in a predetermined ratio to a number of pulses emitted by a pulse transmitter during the rolling operation. This ratio is such that a predetermined upper and lower tolerance limit for the number actually emitted during the rolling operation is set and stored. During a screw-thread rolling operation, the emitted number of pulses is counted and is compared with the upper and lower tolerance limit. If the number of emitted pulses is below the lower tolerance limit and above the upper tolerance limit, the incorrectly rolled product is separated from the correctly rolled products and is conveyed away. The indication and sorting out of incorrectly rolled products thus takes place automatically.
